Thread Synopsis: When powering up the kit after completing the build, and having passed all the tests done during the assembly, the LEDs would usually be unlit with the occasional few coming on and remaining static. No sound, no response in any mode, but clearly getting some kind of power.
Solution: The J3 Molex header was on backwards (pin 1 soldered in at the pin 12 position) on the I/O Board.
Thanks again to MMM (aka The x0x Don, aka Sanity Saver)
First, I just want to say I'm really impressed with the wealth of knowledge and helpful people in these parts - it's extremely refreshing.
So, I built my first x0xb0x (bought the Willzyx kit), but am having trouble after completing the control board. The analog section seems to work fine (I did all the tests during the build, and all worked fine). I soldered FT232 myself (should have paid the $25!) and miraculously it was recognized when plugged into my computer. But, after completing the rest of the kit it doesn't power up as expected.
I get a problem similar to the one here -> http://forums.adafruit.com/viewtopic.php?f=12&t=21219
, but my voltages are all over the place! Usually no LEDs are on, but occasionally I'll get a few that stay solid, regardless of what mode the machine is in.
IC3 DC using pin 20 as ground
Pin 9 = -0.14 v
Pin 18, 19 & 40 = 0 v
BA6110 checks out except
pin 6 & 7 = 5.03 v (not 5.3)
I've checked polar component orientation, resistor values, reheated joints, checked for solder bridges, etc... I'm certain there's something I'm not seeing though...
I'm at a loss, but will not give up! I don't have a lot of electronics knowledge (built a few synthrotek kits and a shruthi-1) but I'm ready to learn and would like to understand why this kit isn't working and how to fix it.
Any help is greatly appreciated! I need a direct dose of acid to my ears ASAP, haha!
